DATING-BOX FOR SELF-INKING HAND-STAMPS.

SPECIFICATION forming part of Letters Patent No. 289,475, dated December 4, 1883,

Application filed January 30, 1883. (No model.)

To all whom it may concern,

Be it known that I, GEORGE VAN ZANDT, a citizen of the United States, residing at Bavenswood, in the county of Cook and State of Illinois, have invented a new and useful Dating BOX for Self Inking Hand Stamps, of which the following is a specification.

My invention relates to a mode of fastening the dating-box to the oscillating die-plate.

The objects of my invention are, first, to

expedite the changing ofdates; second, to level the dates accurately and adjust them to the height of the die; and, third, to permit the dating-line to be used separately (as a padstamp) when desired. I attain these obopen, and the sides may be bent as desiredto fit the type.

D is a spring, formed as shown, and passing loosely through small sleeves attached to the box 0.

E is anotch in each end of the spring. The

notch fits a groove seen on the nut F. F, a 5 grooved nut, adjustable upon screw G; G, a small screw or stud riveted in the plate A.

The action is as follows: The spring, taken by the thumb and finger, is compressed, and its ends are loosened from the nuts. The box, 0 being lifted out of the rectangular opening, may be used as a pad-stamp independently, (the spring serving as a handle,) or the date in the boX may be changed, and when replaced in the die-plate the liberated spring will keep 5 it there. The line is leveled and adjusted by turning the nuts on the screw-thread.

I am aware that previous to my invention a device showing dating -type in an endless band on a metallic shell inclosing a spring by 50 which it is attached to lugs on the die-plate has been patented, and self-inkin g hand-stamps I have been made having dating-type inserted through an opening in the die-plate, and I do not claim any such combination broadly; but 55 \Vhat I do claim as my invention, and desire to protect by Letters Patent, is-

The combination, in a self inking handstamp, of the plate A, having the opening B, the screw-studs and the grooved nuts F with the type-box 0, having small sleeves, and the spring D, passing through the sleeves and engaging with the grooved nuts, all substantially as shown.

GEORGE VAN ZANDT.
